Learn2 Combat Jet
Lag

Flying in the face of the traveler's
bugaboo
It's four in the morning, and you're tossing and
turning between crisp hotel sheets. Then a few
hours later, just as you're walking into the big
meeting--important enough for you to cross six time
zones--you're finally ready to fall asleep. For the
next two weeks.
It's every traveler's nightmare. As people fly
more and more, both for business and pleasure,
circadian dischronism (otherwise known as jet lag)
is becoming something of an epidemic. Beside
exhaustion and insomnia, symptoms of jet lag
include nausea, aching joints, irritability,
decreased concentration, headaches and even
depression.
Fortunately, science is making inroads into the
mysteries of jet lag, and researchers have
developed a number of active steps you can take to
alleviate its symptoms. If you follow the
guidelines outlined in this 2torial, you'll find
yourself less shell-shocked, happier and more
productive when you reach your final destination.

The body's clock is an incredibly complicated
mechanism. Because so many factors--both biological
and environmental--are involved, scientists have
been unable to find a silver-bullet cure for jet
lag. Yet research shows it is possible to alleviate
symptoms by gradually "tricking" the mind and body
into abiding by the new time zone.
Conventional wisdom says that it takes one full
day to recover from jet lag for every time zone you
cross. So, if you travel across seven time zones
and don't take active steps to fight jet lag, you
can expect to spend a full week recovering from the
shock. However, you may be able to speed up the
process if you take the following steps.
Arrive at the airport in fighting
form
The battle begins before you even set foot in
the airport. You can do a number of things to
prepare in the days leading up to take-off,
including:
Sleep well: Get plenty of sleep in the
nights leading up to your big trip--it may be the
single best thing you could do. Of course, jet lag
is not simply a lack of sleep; it is the desire to
sleep at the wrong time. But if you are
well-rested, you will suffer less from fatigue and
exhaustion when these symptoms hit. In addition,
you'll have extra energy if you need to stay up
late in order to adapt to the new time.
Plan meals and bedtime: If possible, plan
meals and bedtime as if you were already in the new
time zone. Yes, that probably means going to bed
when you're not sleepy, or getting up before it
feels right to do so. But even if you can only
adjust your schedule by an hour or two, you may in
turn shrink your jet lag by a day or two.
Some die-hard travelers swear by the Argonne
National Laboratory Anti-Jet Lag Diet, which
consists of a three-day regime of feasting and
fasting. Developed by U.S. government researcher
Dr. Charles F. Ehret, the diet is said to work
because high protein breakfasts and lunches
stimulate the body's active cycle while a high
carbohydrate dinner stimulates sleep. By fasting,
you deplete the liver's store of carbohydrates and,
according to scientists, prepare the body's clock
for resetting. Anecdotal evidence suggests that
this diet can be quite effective, but research
remains to be done. Here's the breakdown:
Day One: Feast. High-protein breakfast
and lunch (lots of eggs, cheese or meat), followed
high-carbohydrate dinner (consisting mostly of
bread, rice, fruits and vegetables, and pasta).
Day Two: Fast (three light meals totaling
less than 800 calories).
Day Three: Feast (same as Day One).
Day of Departure: Fast. Break your fast
with a high-protein breakfast at the first normal
breakfast time in your destination.

Set your watch to the new time zone: As
you board the plane (or even earlier if practical),
set your watch to the new time zone. It sounds too
simple to be true, but in fact, experts say this
can give you a very real head start on the recovery
process. Why? Because it'll encourage you to make
decisions about eating and sleeping that are in
line with the new time zone before you even arrive.
Avoid stress: Try to arrive at the
airport relaxed. This will allow you to make wiser
decisions about eating sleeping and drinking, and
will be especially helpful if you need to sleep on
the flight.
Abstain from alcohol the night before: A
hangover not only closely resembles jet lag, it can
compounds its effects. Like jet lag, alcohol can
also upset the body's natural circadian rhythms
(your sleep patterns).
Fly right
The symptoms of jet lag can be amplified by the
effects of flying itself, namely dehydration and
pressure changes. So you should take steps to avoid
the stresses and strains that accompany even the
shortest flight, including:

Drink plenty of water: The air in planes
is so dry that it can actually dehydrate you.
Experts say you should drink eight ounces of water
for every hour you fly to make up for the On long
flights, bring an extra liter of water, since busy
flight attendants may not provide you with as much
water as you need.
Exercise and stretch: Small seats and
pressure changes can cause swelling and muscle
cramping, which can in turn aggravate symptoms of
jet lag. By stretching in your seat and walking
around the cabin from time to time, you can keep
the blood flowing the muscles limber.
Avoid alcohol: Alcohol may soothe your
nerves in the short term, but it will fray them in
the long run if you over-indulge. Alcohol increases
dehydration, and--as we said previously--a hangover
makes everything worse.
Get the right amount of sleep on the
plane
If you arrive at your final destination in the
morning, you'll want to get off the plane as rested
as possible. Otherwise you might head straight to
bed while the rest of the world goes about its
business.
However, loads of sleep during the flight can
actually be counter-productive if your flight
arrives in the evening: you'll be so rested that
you can't fall asleep--until the following morning.
In this case, it's better to arrive tired enough
that you'll sleep no matter WHAT time it is.

Getting sleep
Board the plane armed with the following: an
eye-shade to block out light; ear-plugs to shut out
sound; and an inflatable neck-rest for comfort. In
addition, pack a high-carbohydrate snack such as
fruit, candy or bread products--it's more likely to
induce drowsiness than one that's high in protein.
Finally, wear loose clothing and dress in layers.
If it gets too warm, you'll be able to shed a
layer. Also, bring a warm sweater or sweatshirt
just in case it gets chilly.
You may want to consider taking melatonin, a
hormone that some people find to be an effective
sleep aid over the short term. It's widely
available in drug stores, health food stores and
now even grocery stores. A prescription isn't
necessary, but as with any pharmaceutical, you
should consider consulting a physician before
trying it.
You might also consider taking a sleeping pill,
but you should always consult with a doctor before
doing so. Sleeping pills can be risky, especially
when taken at high altitudes. Avoid taking either
sleeping pills or melatonin for more than short
periods of time.
Avoiding sleep
Planes seem designed to prevent sleep, but you
still may need some extra help. Bring along a
stimulating activity, whether it's a mystery novel,
your taxes, or a pack of cards. When you start to
dose, get up and walk around the cabin, splash some
water on your face, or engage willing neighbors in
conversation. Pack a high-protein snack, for
example unsalted nuts or boiled eggs, and drink
some caffeine (coffee or soft drinks are typical
choices) if necessary--though whether or not you
want to consume caffeine depends on your own diet.
Needless to say, avoid drinking caffeine as you
approach your destination, or you may be too
stimulated to fall asleep once you arrive.
Abide by your new time zone
Your body may fight you, but when you arrive in
Rome, do as the Romans. That is, sleep and eat
according to the new time zone, not the old one. If
your flight touches down at eight in the morning
and you head straight to bed, you can be sure that
you'll be wide awake at four the next morning. If
you absolutely must get some sleep, limit yourself
to a nap of less than two hours. If you're starving
at three in the afternoon, have a light snack and
wait until dinner-time for a real meal. Other steps
you can take include:

Heading outside: Daylight has a direct
effect on the body's circadian rhythms, and walking
outside can help you stay awake until bedtime and
at the same time give you jump start in adjusting
to the new time zone.
Getting exercise: Like daylight, moderate
to vigorous exercise will give you more energy and,
if necessary, help you stay awake until the evening
hours. In addition, evidence has been found that
exercise allows the body's circadian rhythms to
adjust more quickly. If you can't spend an hour on
a treadmill, take long walks (perhaps you'll be
able to take in some sights on the way!).
Sleep aids at bedtime: When it's bedtime
in your new destination, and you find yourself wide
awake, get between the sheets, turn out the light
and try to sleep anyway. The wear and tear of
travel might just catch up with you. Also consider
stretching, meditating, taking a hot bath, or
engaging in any other activity that deeply relaxes
you.
If none of these tricks yields results, you
might consider taking melatonin or a conventional
sleeping pill for the first night or two, just to
get back on schedule. But only do so under the
guidance of a physician.
Like the common cold, jet lag has stealthily
eluded a sure cure. But even if science never
defeats circadian dischronism, you might be able to
battle it to a draw--with a little strategic
planning.
